Conical Update

A few weeks ago I got a conical fermenter and assembled it to brew my Mild. It worked fairly well except that there was no way of knowing the temperature of the fermentation with out removing the airlock to insert a thermometer, which defeats the purpose of a conical to keep oxygen out of the beer. This past weekend I brewed a fresh hop beer with 1# of wet Simcoe hops, and 1# of wet Citra hops in the last 15 minutes of the boil. While that was cooling I cut a hole in the top of the conical to fit a small rubber bung, and forced (quite difficultly) a thermometer through the bung into the fermenter. This will give me the ability to know the exact fermentation temperature of the beer inside the fermenter. Now I just need to get a different thermometer since my spare only reads in 5 degree increments as opposed to 2 degrees like my other one, meaning that 71F and 74F look almost the same, yet are worlds apart in the world of ale fermentation. Next up is a sample port so I can keep the system fully closed until packaging or secondary additions, and then a stationary insulated chamber for temperature control.
